Jiz/m/es H B z/Q W) Patented May 12, 1931 UNITED STATES PATENT OFFICEJAMES H; BOYE, 'OF CHICAGO, ILLINOIS, ASSIGNOR TO JAMES H. BOYEMANUFACTUR- ING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOISCURTAIN SUPPORT Application filed May 21, 1930. Serial No. 454,246.

This invention relates to curtain fixtures,

having reference mainly to curtain supports .known as the pull cordtype, wherein mating right and left sections of the curtain or portiereare suspended from a rod and are drawn together or apart at their upperends by a cord trained over guide pulleys or sheaves in or on the rod,said cord being attached'to and operating a pair of master hanger slidesfrom which the upper ends of the inner marginal portions of the twocurtains are suspended. The present invention relates more particularlyto improvements in the curtain hanger slides; certain of thepresent'improv'ements pertaining to the master slides of a pull cordtype of curtain fixture, while other improvements are applicable tocurtain suspension slides generally whether of the pull cord type or ofthe plain type wherein thecurtain is manually drawn back and forthlengthwise of the rod.

One object of the present invention, insofar as the latter relates tothe master slide, is to provide a very simple, inexpensive and efficientcord clamping device for connecting the slide to the cord and readilyadjusting the slide to its proper position on the cord. Still anotherobject of the invention, insofar as the latter relates to hanger slidesgenerally, is to provide an improved construction which will revent thesuspension arm of the slide to whlch the upper edge of the curtain isattached from rubbing on the lower edge of the curtain rod itself, thuspreventing the frictional drag which would otherwise occur and alsoavoiding the scratching and marring of the surface finish of the rod.

My present invention, in one approved form in which the same may beembodied, is illustrated in the accompanying drawings, in which Fig. 1is a front elevational view of a fragment ofa curtain rod and the upperportion of a curtain, showing my improved curtain hanger slideassociated therewith.

. Fig. 2 is a rear elevation of the parts shown in Fig. 1.

Figs. 3 and 4 are vertical sectional details taken on the lines 33 and44, respectively, of Fig. 1.

Fig. 5 is a perspective elevation of one of the master slides.

Referring to the drawings, 10 designates as an entirety a fragment ofthe curtain rod. As shown in the sectional views, Figs. 3and 4, this isa hollow sheet metal rod of the well known fiat type of substantiallyC-form in cross section. In the present instance I have shown a modifiedform of such a rod wherein internal hollow ribs 11 are rolled in the topand bottom edges of therod, thereby forming front and rear channels 12and 13 having certain functions which are set forth in a companionapplication filed concurrently herewith, Serial No. 454,245. For thepurposes of the'present invention, however, this particular form of arod is not essential, and may be substituted by the known plain C typeof rod.

At 14 I have shown a fragment of the upper portion of a curtain orportiere that is suspended from the rod 10 by the improved hanger slidesofthe present invention; 15 designating as an entirety one ofthe centralmaster slides to which the pull cord is at tached, and 16 designatingone of the plain follower slides.

v Describing the improved master slide 15 in detail, and referringparticularly to Fig. 5, 17 designates a fiat plate, in the upper portion.of which are mounted a pair of rollers 18 which ride in the bottomgroove of the rear channel 13 of the rod; the rollers being of suchdiameter that their upper portions enter the upper grooved channel 13 sothat the rollers are sustained laterally by the walls of said uppergroove and thus maintained in a vertical position. Integral with eachroller- 18 is a short lateral hub or boss 19 that extends through theslot in the rear side of the rod but is out of contact with the edges ofsaid slot, and on the outer end of the boss or hub 19 is a flange 20 ofsufficient diameter to overlap the edges ofthe slot. Each roller 18 andits boss 19 are fast on a central spindle 21, which latter projectssufficiently beyond the boss 19 and its flange 20 to form a support forthe hanger plate 17 that is loosely mounted and suspended thereon. Thelower portion of the hanger plate 17 is forwardly ofiset as shown at 17to a position beneath the rod and is formed with holes 22 by which itmay be stitched or otherwise secured to the curtain 14. The purpose ofthe flange 20 is to act as a guard to prevent the hanger plate 17 fromrubbing against the lower portion of the rear wall of the rod as thecurtain is drawn lengthwise of the latter, thus avoiding the frictionaldrag and the wear on the rod that would result from such rubbingcontact. Curtain fixtures of the pull cord type commonly employ a cordfolded on itself to form a long narrow loop extending lengthwise of thecurtain rod, and two end portions that hang from guide pulleys at oneend of the rod. The closed end or bight of the loop is trained around apulley at the other end of the rod, and the two limbs of the loop arerespectively attached, either directly to the inner top corners of amating pair of ourtains, or to a pair of master slides that are attachedto such inner top corners of the curtains; so that a pull on one of thedepending end portions of the cord draws the curtains apart, and a pullon the other depending end portions ofthe cord draws the curtains towardeach others. A good illustration of this type of pull cord curtainfixture may be seen in Figs. 6 and 7 of patent to Datter, No. 924,892,June 15, 1909. A tongue 23 is cut and bent forwardly on an incline fromthe plate 17 and this tongue is formed with a slot 24 extendinglengthwise thereof for the passage of one limb only of the pull cord 25therethrough; it being understood that the other limb of the pull cordpasses below or in front of said tongue 23, as shown in Fig. 4, andpasses through the slot of a similar tongue of the matin master slide(not shown), which is attac ed to the other ourtain. In the plate 17 ofeach master slide adjacent to the base of the tongue 23 is a tappedhole, through which is entered a clamp screw 26, the free end of whichis adapted to bite the cord between the inner end of the screw and theforward end wall of the slot 24 whereby the slide is securely attachedto the cord, but may be readily adjusted lengthwise of'the latter bybacking off the screw 36, adjusting the slide to a new position on theslide, and retightening the screw 36.

Thefollower slide 16 is structurally iden-- tical with the master slideabove described, except that itemploys but a single roller, and

a a narrow han er arm 17" attached at its lower end to t e upper end ofthe curtain, and omits the cord clamping means of the master slide. Thisarm 17 a is held from frictional engagement with the lowerrod itself aby a flange guard 20' structurally and functionally similar to theflangeguard 20 of the master slide hereinabove described.

B cutting and bending the tongue 23 out of tile stock of the hangerplate 17, a considerable economy of labor and material is effected;although, within the purview of the invention, this tongue might be aseparate member attached to the plate. The adjustment of the slide alongthe cord is very easily and quickly effected by simply loosening thescrew 26, sliding the master slide to a new position, and thentightening the screw. And the provision of the guard flange 20 or 20between the hanger plate or arm 17 or 17 and the lower rear edgeof therod makes the drawing of the curtain back and forth very easy byeliminating friction of the plate or arm 011 the rod; and this freedomfrom friction is further enhanced by the provision of rollers having arolling fit in the channel of the rod.

I claim:
